The 1997 UBC, Chapter 22, Division VIII has a specification for Lateral
Resistance for Steel Stud Wall Systems.

Subject: Light Gauge Steel Seismic Design


There are no seismic provisions provided in the AISI 
specification to design light gauge steel members 
(members with thicknesses less than 3/16").  Is anyone 
aware of any studies that have been performed or will be 
performed to assess the performance of light gauge steel 
elements under cyclic or earthquake loading?  

It certainly seems that light gauge steel seismic 
provisions should be in place prior (considering local 
buckling, etc) to the use of any light gauge steel 
system.  Typical steel design (more ductile than light 
gauge steel) requires special design considerations 
(AISC Seismic Provisions, the yellow book) when used as 
a lateral force resisting element for earthquake loading.
